GAS-LAMP.

SPECIFICATION forming part of Letters Patent No. 779,618, dated January 10, 1905.

Application filed October 6, 1904. Serial No. 227,451.

To aZZ whom, it may concern:

Be it known that I, ALBERT W. NIoHoLLs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gas-Lamps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gas-lamps, and more particularly to a gas-lamp adapted to be used either as a table-lamp or as a wall-lamp, means being provided whereby the lamp will rest firmly upona table or stand and means whereby the lamp may be readily hung against a wall, the burner being provided with means for adjustment to a vertical plane at whatever position the lamp-body may occupy.

One of the principal objects of my invention is to provide a convertible lamp of the character referred to which will be simple in construction, comparatively inexpensive to manufacture, and which may be adjusted quickly and which will rest firmly in any position it may be made to occupy. These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which Figure 1 is a vertical sectional view of a lamp made in accordance with my present invention. Fig. 2 is a similar view of a slightlymodified form of the same. Fig. 3 is a still further modification of the head or burner portion of myinvention, showing the same in section as applied to a lamp similar to that shown in Fig. 1. Fig. 4 is a side elevation of a gaslamp made in accordance with my invention and provided with means for automatically holding the burner in a vertical position when the lamp is either attached to a wall or resting upon a table or stand. Fig. 5 is a side view illustrating one position which the lamp may assume when supported from a wall. Fig. 6 is a side elevation of a still further modified form of my invention, and Fig. 7 is a similar view of the lamp shown in Fig. 6 when attached. to a wall.

Referring to the drawings for a more particular description of my invention, the numeral 1 denotes the hollow base or bracket portion of the lamp, and, as shown throughout the drawings, the base is provided with apertures 2 at diametrically opposite points in the lower flange thereof. In the side wall of the base an opening 3 is formed to admit the flexible tubing 4:. As shown in Figs. 1, 2, and 3, the tubular upper end of the base 1 is threaded, as at 5, and in Fig. 1 a spirallycorrugated tube 6 is fitted within the upper end 5 of the base 1, and at the upper end of said tube a burner-head is provided, which comprises a threaded tubular portion 7, having oppositely-disposed circular bearingplates 8 upon its upper side and an interior flange or collar 9. Fitted to move radially between the plates 8 is a burner-holder 10, pivotally connected, by means of the thumbscrews 11, to the plates 8 and having an enlarged or loop portion at its upper end. The flexible tube 4, which is connected at one end to a gas-supply pipe, extends into the opening 3, through the base, up through the corrugated tube 6, and at the upper end of said tube a suitable fitting 12 is connected to the tube, the upper end of said fitting 12 being connected to a threaded nipple 13, designed to receive an ordinary or any preferred form of gas-burner.

When it is desired to use a lamp constructed as described as a wall-lamp, it is merely necessary to turn the burner-holder 10 to a position at right anglesto the tube 6. The lamp may then be supported from a wall by suspending the same from hooks, screws, or other means passing through the apertures 2 in the base of the lamp.

It is very desirable in this class of gas-lamps to provide means whereby the jarring or slight vibratory movement of the lamp may be obviated. This is especially desirable in manvibrations which would cause injuries to the mantle.

As shown in Fig. 3, the burner-holder is connected directly to a nipple 15, extending through a cap 16, secured to the upper end of the tube 6, said burner-holder comprising a lower section 17 and an upper section 18, connected together by lapped flanges 19 in a man ner to permit a free swinging movement of the upper section 18 relatively to the lower section 17 in order that the lamp may be converted from a stand-lamp to a bracket-lamp. A thumb-screw 20 is utilized for holding the parts firmly in adjusted position.

As shown in Figs. 4:, 5, 6, and 7, the burner portion of the lamp is designed to automatically assume a vertical position whenever the base portion is secured or suspended from a Wall.

in Figs. 4 and 5, 21 is a counterweight through which the flcxi ble tube 6 passes. Connected to the upper end of the counterweight 21 is a yoke or bearing 22. Pivoted at 23 to said yoke are oppositely-disposed arms 24, the lower ends of said arms being rigidly connected to the base, as at 25. \Vhen the base 1 is swung to the position shown in Fig. 5, the counterweight will by gravity hold the burner portion in a vertical plane.

In Figs. 6 and 7 the counterweights 21 are of a pendent character, being connected to the burner portion of the lamp by a yoke 22, the base portion being pivoted at 23 to said yoke in order that the lamp may assume the position shown inFig. 7 when utilized as a wall or bracket lamp.

It will be obvious that the flexible tube 6 may be connected above the bottom of the counterweight 21 in the construction shown in Figs. 4 and 5 of the drawings by means of an ordinary nipple connection.

From the foregoing it will be obvious that a lamp constructed in accordance with the foregoing invention may be readily converted from a vertical stand-lamp to a horizontal bracket-lamp and suspended from a wall, the burner always occupying a vertical position. It will also be apparent that by means of the construction illustrated in Fig. 2 the injurious vibrations which injure mantle-lamps will be absorbed or taken up by means of the spring 1 1.

My construction is comparatively simple and inexpensive to manufacture, is not liable to get out of order, and will be found very convenient and eflicient for its purposes.

Various changes in the shape, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claimas new, and desire to secure by Letters Patent, is-

1. Agas-lampcomprisingahollowbaseprovided with means for connectingit to a wall or vertical support, a burner-holder connected to the base, a flexible tube extending through an aperture in the base and connected to the burner-holder, and a pivotal connection between the burner-holder and base to permit the bu rner-holder to occupy a vertical position when the lamp is used either as a bracket or stand lamp, substantially as described.

2. A convertible stand-lamp and bracketlamp comprising a hollow base having means for connecting it to a wall, a burner-holder, a tubular connection between the burner-holder and base, a pivotal connection between the burner-holder and the tubular connection, and a flexible tube extending into the base and through the tubular connection to the burnerholder, substantially as described.

3. A convertible stand-lamp and bracketlamp comprising a base or support having means for connecting it to a wall, a spring connected to the base, a burner-holder connected to the spring, means whereby the burnerholder may be moved "from a vertical to a horizontal position, and a flexible tube extending through the base and spring and connected to the burner-holder, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALBERT \V. NIOHOLLS.
